Leading the auction will is Alexander Gilkes, co-founder of the online auction house Paddle8. One of his firm’s more recent hires was Princess Eugenie, daughter of Britain’s Prince Andrew and Sarah Ferguson.

Part of Vanity Fair’s International Best-Dressed list, Gilkes is also family friends with the Middletons and was a guest at Kate Middleton’s wedding to Prince William.

On Friday night, he’ll be wielding the gavel, selling art works by top-name artists. Proceeds will go to the MTV Staying Alive Foundation and the Dallas Contemporary.

Homegrown supermodel and rockstar ex-wife Jerry Hall (the former Mrs. Mick Jagger) will lead the list of A-listers coming to the third annual MTV RE:DEFINE art exhibition, auction and gala on April 4 at the Dallas Contemporary. Goss-Michael Foundation founder Kenny Goss and executive director Joyce Goss (Kenny’s sister-in-law) are co-chairing the event that will feature works by artists Sarah Lucas, Mat Collishaw, Jim Lambie, Julian Schnabel and Richard Phillips. Proceeds go the MTV Staying Alive Foundation and the Dallas Contemporary.

The big news is the donation from Damien Hirst. The dean of the Young British Artist (YBA) movement, Hirst has given a work to be sold at the event. (In 2008, an entire exhibit by Hirst was auctioned at Sotheby’s for a record $198 million.)

Also up for bid will be two personal VIP tickets to Elton John’s Million Dollar Piano Concert in Vegas complete with a meet ’n’ greet with Elton.

Effusive Swiss auctioneer Simon de Pury had the crowd so whipped up at Saturday night’s RE: DEFINE art auction that he extracted more than $1 million from bidders who couldn’t raise their paddles fast enough.

The benefit for the MTV Staying Alive Foundation was at the Goss-Michael Foundation and executive director Joyce Goss was determined to purchase one painting by Michael Craig-Martin. “He’s sort of the godfather of YBA [that’s Young British Artists],” explained Joyce.

No sooner had she bid $50,000 than she saw her brother-in-law Kenny Goss, founder of the Goss-Michael Foundation raise his paddle and bid $55,000.

“I don’t think he knows I’m bidding,” she said.

After she gave him a loving, but stern “cut it out,” look, he demurred and she got the piece for $60,000.

For another auction item, Dallas Symphony Orchestra maestro Jaap van Zweden offered to conduct the Dallas Chamber Orchestra at a private concert in the winning bidder’s home. “If you pay enough,” van Zweden said, “I may teach you to conduct so you can conduct your own piece.”
